Abstract
An actuator device for bidirectional adjustment of an adjusting body constructed for interaction with an adjustment partner and preferably realized as a tappet (), having first adjustment means (), which have expansion means having a magnetically effective shape-memory alloy material () and exerting an adjustment force, particularly a pushing force, on the adjusting body for moving the same along a first adjustment direction, which carry out an expansion generating the adjustment force as a reaction to a first energizing of first coil means (), and second adjustment means () assigned to the adjusting body and provided separately from the expansion means and the first coil unit, which are constructed for moving the adjusting body in a second adjustment direction opposite to the first adjustment direction, characterized in that the second adjustment means have an electromagnetically or electromotively driven actuator and therefore for moving the adjusting body in the second adjustment direction construct a drive, which can be activated as a reaction to signal loading, particularly a second electrical energizing.
